Problems solved by technology

[0004] The purpose of the present invention is to solve the shortcomings in the prior art, such as: when we use it, the fan blades often cannot rotate, and we need to rotate the fan blades by hand or with auxiliary tools before they can rotate. It is because the lubricating oil on the bearing of the electric fan solidifies and dries out due to the high temperature during long-term use, which makes the shaft unable to rotate and causes the motor to be easily burned

Abstract

The invention discloses a rotating head of a household electric fan. The rotating head comprises a shell. A motor is mounted in the shell. A rotary shaft is mounted at one end of the motor. A baffle is mounted on the shell. A bearing is mounted on the baffle and is an oil-containing bearing of a traditional fan, and the bearing and the rotary shaft are located on the same axis. One end of the rotary shaft penetrates through the bearing and is provided with fan blades. A round hole is formed in the outer ring of the bearing. A second sponge pad is mounted in the round hole. A first delivery pipe is connected onto the second sponge pad and is mounted at the bottom end of one side of a storage box. According to the rotating head, a T-shaped pressing plate slowly moves downwards, so that lubricating oil is slowly squeezed to enter the second sponge pad from the first delivery pipe; and the rotary shaft is closely attached to one side of the second sponge pad so that the lubricating oil onthe second sponge pad can be evenly smeared on the rotary shaft when the rotary shaft rotates, the lubricating performance is improved, and the situation that the fan blades do not rotate is prevented.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a rotary head of a household electric fan. Background technique [0002] Electric fans are one of the most commonly used appliances in household appliances. Although air-conditioning fans are slowly being used, traditional fan blades are still the mainstream. [0003] When we use it, the fan blades often cannot rotate. We need to turn the fan blades by hand or with auxiliary tools before they can rotate. It solidifies and dries up, causing the shaft to be unable to rotate, causing the motor to be easily burned. Contents of the invention [0004] The purpose of the present invention is to solve the shortcomings in the prior art, such as: when we use it, the fan blades often cannot rotate, and we need to rotate the fan blades by hand or with auxiliary tools before they can rotate. It is because the lubricating oil on the bearing of the electric fan solidifies and d...
